Over the last few years I have been involved in the history and events surrounding the prison at Strangeways in Manchester, some of which can be seen here
http://www.manchester-family-history-research.co.uk/new_page_26.htmand has some facts about the case.
I have on several occasions used the Freedom of Information Act to try to gain facts. I managed to secure the burial details of those prisoners executed at Strangeways and what happened to their remains. However what happened to the remains of one individual is a mystery, that being Herbert Roy Harris executed for murder in 1952. It seems from the Strangeways burial registers that his remains were exhumed and returned to the family in December 1966.
The question to be asked is why? As far as I can ascertain the remains of convicted murderers were not returned to their families unless a posthumous pardon was given by the Sovereign, and this has only happened three times since 1945. This does not seem to be the case with Herbert Roy Harris.
So why the mystery? I have, one as yet unproven theory. Can anyone give any substantiated incite into this?
